Iron Ore Deposit Classification Based On Type Of Ore

[title]

Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i…Classification of ore deposits - SlideShare,Oct 22, 2017· Descriptive classifications could be very tedious, as each ore body has its own unique properties!

Different Types of Iron Ore - 911metallurgist.com

Sedimentary deposits of iron oxides and hydrous aluminum oxide are of this type. In other cases, the ore deposits (or more precisely ore minerals) may be present in an enclosing rock, called the country rock or the host rock. In such cases, the host rock itself is removed in the first stage of mining.(PDF) Introduction to Sedimentary Ore Deposits,Based on detailed field work in combination with indoor rock geochemical analysis as well as a comparison with typical ore deposits both in China and abroad, the authors carried out restoration of,Magmatic ore deposits (Chapter 2) - Ore Deposit Geology,Magmatic ore deposits, also known as orthomagmatic ore deposits, are deposits within igneous rocks or along their contacts in which ore minerals crystallised from a melt or were transported in a melt. Ore deposits that form in and around igneous rock units as a result of mineral precipitation from aqueous solutions or hydrothermal fluids are hydrothermal ore deposits.

A classification scheme for ore deposits best,

Igneous, Metamorphic, and Sedimentary ore deposits (Fig 1, a, b) Einaudi, (2000),stated that all mineral deposits can be classified into three types based on process, namely magmatic deposits, hydrothermal deposits, and surfacial deposits formed by surface and groundwater.Ore Minerals : What are Ore Minerals? | Geology Page,The ore quality, and density of a rock or metal ore, as well as its occurrence type, can directly affect the ore mining costs. It is therefore necessary to weigh the extraction cost against the metal value contained in the rock to determine which ore can be processed and which ore is too low a grade to be worth mining.Iron and Manganese Ore Deposits: Mineralogy,,The majority of ore deposits of both iron and manganese are of sedimentary origin. At present, high-grade iron ore deposits formed by hydrothermal and supergene enrichment of Proterozoic banded iron formations constitute the most important source for iron ores, with only some magmatic and skarn-type iron ore deposits being mined.
